Best free chess game ever. Gives you an analysis after each game. You can step through each move of the finished game and it shows where you should have moved and indicates if each move is a book move, or the best, good, inaccurate, mistake, or a blunder. it also has example openings you can study. Also, no ads.

The perfect alternative to desktop analysis tools. There are several apps on the market for chess games analysis. However, none of them is as easy to use as Chessis. The UI is very simple, and yet very effective. You can choose to analyze your games based on depth and time. It offers graphs and training tools. I still think that a desktop tool is preferred, but if you need something on the go, if you just played a game on the train and you want to check out your performance, this app is a MUST!

Absolutely the best chess app on Android. Can use some extra features (Maybe some tutorials on book moves and strategies in general, upload custom backgrounds, online matches, etc.). I have not bought pro yet, but for ten dollars, it really isn't much. I have learned a lot from this app, and hopefully will continue to use it for years to come.
